CBN SHARPENING STONE
CBN SHARPENING STONES, RESIN BOND, 100%, 200%, 150-25-5-2 (150-25-5-2)
CBN RESIN BOND SHARPENING STONES
150-25-5-2mm / 6''-1''-0.2''-0.08''

 WE STOPPED PRODUCTION OF THESE STONES AND OFFER INNOVATIVE CBN STONES WITH COMBINED BOND: BETTER PERFORMANCE, LONGER TOOL LIFE AND LOWER COSTS. 

We offer stock of these stones (100% and 200%) for SALE: 70pcs of each grain size (0.5/0 - 200/160). 

Yet, we still continue maintaining some stock of these resin bond CBN stones.
 
CBN (cubic boron nitride) is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite, etc. 
CBN (cubic boron nitride) is the second-hardest material after diamond,  and has the best price-performance ratio for processing steels, comparing to other materials, including diamond, silicon carbide or aluminum oxide.  
Due to it's high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.  


Length: 150 mm = 6 inch
Width: 25 mm = 1 inch
CBN height: 2 mm = 0.08 inch - comparing with 3 mm of new stones
Total height (with blank): 5 mm = 0.2 inch  - comparing with 7 mm of  new stones

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 year), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.

Use and cleaning of diamond sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance is only needed every year or two.
In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl):
- 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 10 mins polish movements (carefully draw "8") on glass plate.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.

You may buy 100 gr. of FeCl in dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.

Use and cleaning of diamond sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl. FeCl, on glass plate is the cheapest and simplest.

You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.
